Install Error Message: ZASS-1043-English has encountered a problem and needs to close

I've been running ZA for about 10 years now, and this is my first major headache with it.
It always ran great until this version 8 install problem and the subsequent uninstall.
I can't reinstall ZASS version 7 or 8 on my Dell Inspiron 9300 w/XP Pro.
After the long shutdown hang times with 8.0.59, I uninstalled it
using the suggested procedure here:http://forum.zonelabs.org/zonelabs/b...ssage.id=82455
I run
zaSuiteSetup 70 483 000 en.exe from my desktop and I
get the following response:
An Initilizing window, then an error report window that states, &quot;ZASS-1043-English has encountered a problem and needs to close. We are sorry for the inconveniance.&quot;
&quot;Would you like to send this report to Microsoft?&quot;
I clicked on the Debug feature on the error window, no help.

I even tried uninstalling XP SP3 and reinstalling ZASS with SP2, but no help.
I reinstalled SP3, no change.
I have no background security scan program running, matter of fact I have no Anti-virus now, and all I have is the Windows XP firewall.
I consider my notebook not useable now until ZASS is reinstalled.
Could
some ZASS guru
provide me with a
suggested fix?
Thanks.

I did have the MS firewall turned off, but that did not help.
Thanks.
I just tried a System Restore from last Friday, and the result allowed ZASS 7 to install.
I'm staying away from ZASS 8 like the plague.
